Welcome, Anders.

That is a problem that we encounter all the time in Australia, where there
are huge expanses of empty, & official OSM guidelines mean that not much
shows :-( Can be worked around to a certain extent by tagging for the
renderer by upping villages / hamlets to towns & making country roads
highway=trunk but officially not approved.

Assuming of course that we're talking about the same thing - areas on the
side of the road where gravel was dumped while road work was taking place?
eg
https://www.openstreetmap.org/edit?relation=6007743#map=19/-36.41030/148.59385
or
https://www.google.com.au/maps/@-28.169598,152.8911178,3a,27.7y,206.26h,88.62t/data=!3m6!1e1!3m4!1shrpfOqOyE4oBith4P7iQzQ!2e0!7i13312!8i6656?hl=en
(NB not the same spot! & G Maps used as an example only , not for mapping
blah, blah, blah ...)

These were discussed in the Australia list a little while ago:
https://lists.openstreetmap.org/pipermail/talk-au/2020-February/013632.html
with no real consensus but landuse=stockpile + resource=aggregate (gravel /
sand / rock etc) was fairly well received.

Unfortunately, though, that won't render :-(, although a counter suggestion
of landuse=industrial + industrial=stockpile + resource=*** would :-)

Good luck!

Thanks
